Yeah, a .454 Casull will tear up a low buck scope. Take a look at the Leupold FXII "handgun" scopes. They MSRP for $439, but you can usually find them for $100 less at places like opticsplanet. Burris makes a "Posi-Lock" variable handgun scope for about the same price... either scope will hold up to a big boomer quite nicely.
